Chemical Structure

(S)-(+)-Pantolactone CAS 5405-40-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-(+)-Pantolactone.

(S)-(+)-Pantolactone (CAS 5405-40-3) is a high-purity analytical reference standard with the molecular formula C6H10O3 and a molecular weight of 130.14 g/mol.

Structurally, (S)-(+)-Pantolactone (C6H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 130.14 g/mol, it falls into the low-molecular-weight range.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures (S)-(+)-Pantolactone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
